Diesel/ULSD

Diesel hydrotreating primarily involves sulfur removal to low (<500 ppm) or ultra low (10 ppm) levels. In addition to sulfur removal, cetane uplift and poly-aromatic hydrocarbon (PAH) removal is also possible. Hydrotreating diesel can require severe processing, especially when ultra low sulfur is required and the feedstock contains cracked components. The highest activity catalysts are usually required for ultra low sulfur diesel production in order to reach acceptable cycle lengths.

CoMo catalysts are most often specified for diesel and ULSD hydrotreating operations but NiMo catalysts may be preferred in some cases. For ULSD in particular, Albemarle’s STARS™ and Nebula™ technology have been very widely applied. Albemarle also offers process technologies for ultra low sulfur diesel.
